Answer:

Step-by-step explanation:

First of all notice that slope has a negative value

Also notice that line cuts the y axis in -1

because of the symetry of the line you can deduce that the slope is -1, also you can calculate it using the fact that the points (-1, 0) and (0, -1) belongs to the line, the slope would be:

m=(0-(-1))/(-1-0)=-1

finally the equation is

y=-x-1
